Syracuse media report that Steven Pieper, of Liverpool, pleaded guilty Tuesday morning in Onondaga County Court to second-degree murder in November's slaying of 20-year-old Jenni-Lyn Watson.
Pieper admitted strangling and suffocating Watson inside her parents' home in the town of Clay on Nov. 19 and hiding her body in a wooded area in a nearby park.
Watson had returned home from Mercyhurst College in Erie, Pa., for Thanksgiving the day before she was killed. Searchers found her body eight days later.
Under a plea deal, Pieper will be sentenced to 23 years to life in prison on March 8.
